For an LTI system, the Bode plot for its gain is as illustrated in the figure shown. The number of system poles $N_{p}$ and the number of system zeros $N_{z}$ in the frequency range $1\: Hz \leq f \leq \:10^{7} Hz $ is

- $N_{p}=5, N_{z}=2$
- $N_{p}=6, N_{z}=3$
- $N_{p}=7, N_{z}=4$
- $N_{p}=4, N_{z}=2$
